Properties of carbon and sulfur questions

Click For Summary

Discussion Overview

The discussion revolves around the chemical properties and reactions of carbon and sulfur in gunpowder, particularly focusing on their roles as reducing agents and the effects of omitting sulfur from the mixture. Participants also explore alternative substances, such as phosphorus, in place of carbon.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the properties of chemical reactions involving carbon and sulfur in gunpowder and the differences when only carbon is present.
  • Another participant explains that carbon and sulfur act as reducing agents in black powder, while potassium nitrate serves as an oxidizing agent, resulting in heat and gas production.
  • This participant suggests that sulfur enhances combustion speed and shares personal experience of a slower burn when using carbon alone with potassium nitrate.
  • A different participant raises a question about the potential chemical reactions if phosphorus were used instead of carbon.
  • One participant notes that discussions on explosives are not permitted on the forum.

Areas of Agreement / Disagreement

There is no consensus on the specific chemical reactions or properties discussed, and multiple viewpoints regarding the roles of sulfur and alternative substances remain. The discussion also acknowledges the forum's restrictions on discussing explosives in detail.

Contextual Notes

Participants express uncertainty regarding the specific effects of omitting sulfur and the implications of using phosphorus instead of carbon, with no resolution on these points.

what is the properties of chimcal reaction for carbon and sulfur in gunpowder...and what different reaction happens if the gunpowder have just carbon without sulfur
 
Chemistry news on Phys.org
The carbon and sulfur in black powder are reducing agents, while the potassium nitrate is an oxidizing agent. The reaction releases lots of heat and gaseous products, which makes it possible to use the mixture as an explosive.

I think the reason why sulfur is added in the mixture is because it speeds up the combustion. I actually once made a mixture of KNO3 and carbon without sulfur, and it seemed to burn like black powder but slower.

Note that in physicsforums we are not allowed to discuss in detail how to make explosives...
 
what a bout if use phosphor instead of carbon...what happen in chimcal reaction...
 
We don't discuss explosives at PF.
